Corded power tools with brushless dc (BLDC) motors or universal motors that operate on dc or ac power require extensive overcurrent, overvoltage, and ESD protection. Littelfuse provides electronics that help ensure the machines operate safely. We also offer extensive portfolios of rectifiers and current transformers designed specifically for use with small, high-speed motors.

Users want cordless power tools to charge quickly and operate reliably without overheating or shocking them. Electronic components made by Littelfuse can help meet those demands. In addition to several ESD protection solutions, we make rectifiers for small brushless dc (BLDC) motors. We also maintain large portfolios of overcurrent and overvoltage protection devices for circuits and battery packs.
